IMPROVEMENT IN HOLDBACK S.-

Specification forming part of Letters Patent No. 177,184, dated May 9,1876; application filed April 1, 1876.

To all whom it may concern:

Be it known that I, WILLARD P. WHITE, of Orland, in the county ofHancock and State ot' Maine, have invented certain new and usefulImprovements in Holdbacks for Vehicles; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, that willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, forming apart of this specification, in which Figure 1 shows a side elevation ofmy invention; Fig. 2, devices for attaching the parts to each other.

Same letters show like parts. j

The object of my invention is to provide a holdback for vehicle-shafts,which, while furnishing a secure support for the holdbackstrap when thevehicle presses forward, shall not retain said strap so as to preventthe passage of the horse from the shafts in case of accident. In suchevent, my device, as will be readily seen, is a great safeguard, besidesbeing a convenience in unharnessing, rendering it unnecessary to detachthe holdbackstraps, that being done by the horse in passing from thevehicle.

My invention consists of a holdback, made in the ordinary form up tothejunction of the hook with the supporting-standard. .The latteris madeof metal, but the retaining-hook is made of rubber or like elasticmaterial. It is sufficiently stiti' to prevent the escape of the strapfrom the motion of the vehicle, but bends and allows it to be withdrawnwhen force is exerted against it. It further consists in the peculiarmanner of attachment of the rubber to the metal portion of the holdback,said rubber portion having a socket therein,

and being stretched over'a projection, and retained by a shoulder andgroove on the iron.

Reference to the drawing will explain my invention fully.

At a is a portion of a vehicle-shaft, having the holdback b thereon, thestandard 0 and brace d of which may be constructed as usual.

The retaining-hook 0, attached to said standard, is, as before stated,of rubber. The dotted lines exhibit its position when drawn out by thestrap.

In Fig. 2 is shown my mannerof attaching the hook to the standard,which, as at f, is

herein described, consisting of a metal standard. in combination with arubber retaininghook, attached to the upper extremity of said standard,and curving inwardly toward the shaft, as shown, for the purposes setforth.

2. In a holdback, the metal portion 0, provided with the projection gand groove h, in in combination with the rubber retaining-hook e, havingthe socket 13 therein, said parts operating as set forth, for thepurposes described.

In testimony that I claim the foregoing I have hereunto set my hand this30th day of March, 1876.
